Windows Embedded Compact implements three different modes for the Simple Network Time Protocol (SNTP): unicast, multicast, or anycast.

SYSGEN_DSTSVC

The daylight saving time (DST) Time Service provides adjustments for daylight saving time updates for applications or services that use a clock.

SNTP Service Configuration

SYSGEN_SNTPSVC

The Simple Network Time Protocol (SNTP) service synchronizes the clock on a Windows Embedded Compact powered device with a time reference available on the Internet. When you include this feature, the time-server registry settings will be included in the run-time image.

With the SNTP service, the device periodically checks the time reference on the time server.
